Question 8
H

Hot iron wool reacts with chlorine gas to form a brown solid, iron(III) chloride.

Which is the correct balanced equation, including state symbols?

[1]
A

Fe(s)+Cl2(g)→FeCl2(s)\mathrm{Fe(s)} + \mathrm{Cl_{2}(g)} \rightarrow \mathrm{FeCl_{2}(s)}Fe(s)+Cl2​(g)→FeCl2​(s)

B

2Fe(s)+3Cl2(g)→2FeCl3(aq)2\mathrm{Fe(s)} + 3\mathrm{Cl_{2}(g)} \rightarrow 2\mathrm{FeCl_{3}(aq)}2Fe(s)+3Cl2​(g)→2FeCl3​(aq)

C

2Fe(s)+3Cl2(g)→2FeCl3(s)2\mathrm{Fe(s)} + 3\mathrm{Cl_{2}(g)} \rightarrow 2\mathrm{FeCl_{3}(s)}2Fe(s)+3Cl2​(g)→2FeCl3​(s)

D

Fe(s)+3Cl(g)→FeCl3(s)\mathrm{Fe(s)} + 3\mathrm{Cl(g)} \rightarrow \mathrm{FeCl_{3}(s)}Fe(s)+3Cl(g)→FeCl3​(s)
